Our Story
Where Strength Meets Community
At NitroFlex, we believe fitness should strengthen more than your body.
It should build confidence. Create connections. Improve the way you move and feel. Give you the support to keep going when progress feels difficult.
That belief is at the heart of everything we do.
NitroFlex Fitness Gym was built to bring the resources of a full-service gym together with the attention, coaching, and accountability of a private training facility. Members have access to quality equipment, group fitness classes, personal training, small group coaching, youth and teen programs, athletic performance training, nutrition support, and open-gym training—all within one welcoming local community.
NitroFlex is built around relationships. Our members are not numbers on a spreadsheet. They are individuals with different goals, experiences, challenges, and reasons for showing up.
We take the time to know them.

Owner of nitroflex gym
Meet Kerri
Dance and movement have always been a big part of Kerri’s life. Growing up on Long Island, New York, she spent years pursuing her passion for dance, building her dance career, and even teaching tap. She studied at the Lee Strasberg Theatre Institute before eventually moving to New Jersey. Her love of dance naturally evolved into a passion for strength training and fitness, giving her a deep appreciation for the connection between movement, confidence, and overall well-being.
As a mother of four, Kerri understands the importance of balancing family, work, and personal wellness. She believes in leading by example and encouraging her children and those around her to make health and fitness a part of their everyday lives.
After serving as the Fitness Director at NitroFlex Gym for almost 10 years, Kerri took the next step in her journey and became the owner. Having spent nearly a decade building relationships with members and being part of the NitroFlex community, she knew just how special the gym was. Her vision was to build on that strong foundation while continuing to improve the facility, expand its offerings, and create an even better experience for its members.
Above all, Kerri wants NitroFlex to be a place where everyone feels welcome, supported, and motivated, regardless of their age or fitness level. Whether someone is stepping into a gym for the first time or has been training for years, her goal is to create an environment where members feel comfortable, challenged, and proud of what they can accomplish.
For Kerri, NitroFlex is more than just a gym. It’s a place where members become friends, confidence is built, and everyone is encouraged to be their best. It’s a community that truly lives up to its motto: “Where Strength Meets Community.”

I am an ISSA Certified Personal Trainer and a Certified TRX Instructor. I have 12 years of experience and have trained clients of all ages and fitness levels.
My passion for strength training came later in life. I was always very active and I’ve always been concerned with being healthy and strong. There is nothing more rewarding than seeing your clients reach their fitness goals and to see their transformation both physically and mentally. You are never too old to start strength training. Exercise not only helps the body but the mind and spirit as well.
Kathy Batsides
NASM Certified Personal Trainer
NASM certified Nutrition Coach
Kathy turned her lifelong passion for health and fitness into a career and has been a Certified Personal Trainer for over ten years. She believes fitness is about more than workouts—it’s about building confidence, staying strong through every season of life, and feeling supported along the way.
Her training style centers on functional, strength-based movement that helps clients feel capable in everyday life. With a strong understanding of how strength training supports bone density, joint health, and long-term mobility, she is especially passionate about helping women build and maintain muscle as they age in a way that feels empowering and approachable.
She works with clients of all ages and fitness levels, creating training that is effective, enjoyable, and sustainable. Being part of a close-knit, community-focused gym allows her to do what she loves most—helping people feel stronger, more confident, and at home in their fitness journey.
